The Great Wall of China is the major structure built during the Ming Dynasty. Although construction of the Wall began earlier, the Ming Dynasty (1368-1644) saw extensive work to fortify and expand it, making the Wall a defining feature of Chinese architecture. The goal was to defend against invasions from northern nomadic tribes and to protect trade routes, including the Silk Road. The Ming Wall is renowned for its impressive scale and resilience, incorporating watchtowers and fortresses along its length. Today, it stands as a symbol of China's historical strength and architectural ingenuity, attracting millions of visitors annually.
